The menu at O Cartaxeiro, located in the heart of Lisbon, reflects a strong coastal Portuguese identity with a satisfying balance between traditional seafood dishes and lighter, fresh options. The standout preparations clearly lean toward the sea, with highlights such as Sardines with Potatoes, Sardines Salad, Sea Bass with Rice, Choco Frito, and the classic Bacalao A Bras, each offering a distinct expression of local flavors, from rustic grilled simplicity to richer, more seasoned compositions. The menu also expands beyond pure seafood with hearty mixed plates like Salmão Y Ternera Con Papas, as well as an intriguingly prepared grilled option in Sarde Alla Griglia Con Contorno Di Riso Saltato In Padella Muy Bonito, which adds a Mediterranean touch with its combination of fish and sautéed rice. For those seeking something lighter, the selection of sides and salads such as Large Salad Plus, Légumes Composés, and even Azeitonas E Cervejas helps round out the dining experience with fresh and shareable elements. Dessert is kept traditionally Portuguese with comforting sweet finishes like Baba de Camelo and Bolo de Nata, offering a soft and creamy contrast to the savory richness of the mains. Overall, the menu feels grounded in regional authenticity while still providing variety for different appetites, whether guests are looking for a simple seafood plate or a more complete, multi-course experience.
